Why flagged

The PKGBUILD fetches the official RPCS3 AppImage from GitHub's official release API (api.github.com/repos/RPCS3/rpcs3-binaries-linux/releases/latest) and executes it only to extract its contents (--appimage-extract), which is the standard pattern for AppImage-based AUR packages. The executed binary comes from the official RPCS3 GitHub releases, not an attacker-controlled host. The sha256sums is SKIP because the version is dynamically resolved at build time (a common but sloppy practice for -bin packages tracking latest releases). The dynamic URL resolution via curl+awk is unusual but not malicious - it simply finds the AppImage asset URL from the GitHub API response. The main concern is the lack of checksum verification (SKIP), meaning a MITM or compromised GitHub release could substitute a malicious binary, but this is a packaging quality issue rather than active malice in the PKGBUILD itself. This is a false positive for HIGH risk.

Triggered rules

Low AI review downgraded a static finding llm_review

The static rules flagged this HIGH, but an AI model (anthropic/claude-sonnet-4.6) reviewed the full PKGBUILD and judged it LOW (confidence 85%): The PKGBUILD fetches the official RPCS3 AppImage from GitHub's official release API (api.github.com/repos/RPCS3/rpcs3-binaries-linux/releases/latest) and executes it only to extract its contents (--appimage-extract), which is the standard pattern for AppImage-based AUR packages.

1 higher static finding superseded - not the current verdict (shown for transparency)

High Downloaded file is executed download_then_exec

A file fetched with curl/wget (not part of source=(), so never checksum-verified) is later made executable or run — a fetch-and-execute pattern split across statements.
